Very good performance and load testing capabilities
There are some compatibility issues with the load standpoint test. When we use the solution instead of Microsoft Edge, more scripting is required. The reports for structure point or test management could be more compatible with other tools. For example, when I create an application I sometimes cannot generate a report.

Cloud-based testing has simplified remote mobile validation and provides flexible device coverage
I was not impressed with how detailed their analytics and logs are from LambdaTest. The solution we were testing is being used because many of us are working from home. It was easy to implement because with a real phone, we have to bring a real phone to each person. Since three years ago, many employees have been working from home, so we were trying to find a solution for this challenge. We had no need to exploit the information for the analytics generated in the background. The purpose was simply to make it easy for our employees to access a phone. The downsides I noticed include that the pricing was very good, but the visual quality of the image sometimes suffers. The contrast on a real iPhone provides better contrast than with the cloud solution. The only aspect that was less favorable than on a real phone was the contrast of the color.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable aspects of the solution are the font, size, and interface."
"The way it identifies elements is good."
"Before using Telerik Test Studio, I was a manual tester, so it was my first automation tool, yet I felt very comfortable using it. I've used the record and play feature, and Telerik Test Studio was easy to use. The tool was easy to understand, even for a first-time user like me."
"Has a very smooth process for launching and closing the application after execution."
"The object repository is the most valuable feature, as different elements can be identified and reutilized through the repository across other scripts, and the product has a very smooth process for launching and closing the application after execution."
"The performance and load testing are very good."
"LambdaTest was handy and easy enough to save us a lot of time, effort, and money."
"LambdaTest has helped me gain more customers."
"Using LambdaTest, we could run all our functionality tests across various browsers, OS, and resolutions."
"LambdaTest Selenium Grid has helped us radically reduce the manual testing effort and ensure browser compatibility."
"Automation and mobile testing have improved our efficiency."
"It's user-friendly and offers valuable features for testing, making it a reliable tool."
"LambdaTest is a saving soldier for our company by offering us thousands of browsers and platforms to test on the cloud."
"It provides 2000+ browser-OS-resolution combinations to work with, which is perfect for our consulting firm, as we don't know what our clients may need."
 

Cons

"The charts need to be more detailed and customizable."
"We have not seen a return on investment yet."
"I observed that the Excel and Word validation was quite challenging, which is an area for improvement in the tool. I also experienced minor difficulties with Telerik Test Studio, particularly in fetching elements in some scenarios when using C# for coding."
"The first time I customized the solution, it was quite challenging."
"It can be improved by including a feature that allows multiple file types to be selected simultaneously."
"There are some compatibility issues with the load standpoint test."
"Its UI is not very user-friendly and could be improved. For new users, it isn't easy."
"LambdaTest needs to have native application testing, which would be a great help to my team."
"Sometimes, when multiple users use the tool simultaneously, it can slow down, affecting efficiency."
"Load flow compared to other stacks needs improvement."
"The execution reporting can be improved for better integration between automation execution and accessibility platform reporting."
"LambdaTest needs to improve its speed and memory because it takes a long time to load."
"We get logged out of the devices if there is some inactivity."

"For us, Cypress! It looks like the support for Cypress is not there."
 

Pricing and Cost Advice
